What is the thickness of the crust layer?

Answer 1

Thickness of Continental and Oceanic Crust

It varies in thickness from around 5 to 100 kilometers. The continental crust is thicker in comparison to oceanic crust. The oceanic crust ranges from 5 to 10 kilometers {average 7 km} while continental crust ranges from 25 to 100 kilometers {average 30-35 km}. Thickest continental crust regions are under large mountain ranges.
